ClearEffect of microplastics on oxytetracycline trophic transfer: Immune, gut microbiota and antibiotic resistance gene responses
When polypropylene microplastics and the antibiotic oxytetracycline were present together in water, the microplastics acted as carriers that increased antibiotic buildup in shrimp and fish through the food chain. This combination caused more gut and liver damage, weakened immune defenses, and promoted the spread of antibiotic-resistant bacteria. The findings highlight that microplastics can make antibiotic pollution worse by helping resistant genes move up the food chain.
The occurrence of microplastic in specific organs in commercially caught fishes from coast and estuary area of east China
Researchers studied how polyethylene microplastics interact with the antibiotic ciprofloxacin in aquatic environments and found that the plastic particles can absorb and concentrate the drug on their surface. The adsorption capacity increased with weathering of the plastic, suggesting that aged microplastics in the environment are more effective carriers of pharmaceutical pollutants. The findings raise concerns that microplastics could transport antibiotics through water systems, potentially contributing to antimicrobial resistance.

Researchers investigated the combined effects of polystyrene microplastics and the antibiotic roxithromycin on red tilapia and found that microplastics enhanced the bioaccumulation of the drug in fish tissues. The co-exposure also produced greater biochemical disruption than either contaminant alone, suggesting microplastics may act as carriers that increase pharmaceutical uptake in freshwater fish.
Interactive effects of microplastics and selected pharmaceuticals on red tilapia: Role of microplastic aging
Researchers compared how aged versus virgin polystyrene microplastics interact with the antibiotic sulfamethoxazole and the beta-blocker propranolol in red tilapia. They found that aged microplastics, which have rougher surfaces from UV weathering, adsorbed more pharmaceuticals and altered their bioavailability to the fish. The study demonstrates that environmental aging of microplastics changes their capacity to carry and release pharmaceutical contaminants in aquatic systems.
The occurrence of pollutants in organisms and water of inland mariculture systems: Shrimp aquaculture is a procession of Microplastics accumulation
This study examined microplastic contamination in water and shrimp at different stages of both pond-based and industrial inland aquaculture systems, finding that shrimp accumulated microplastics throughout the production cycle. The results establish shrimp aquaculture as a notable pathway for microplastic transfer into the food supply.
Implications of polystyrene and polyamide microplastics in the adsorption of sulfonamide antibiotics and their metabolites in water matrices
Researchers found that polystyrene and polyamide microplastics can absorb sulfonamide antibiotics from water, with smaller particles and acidic conditions increasing absorption significantly. This means microplastics in the environment can act as carriers for antibiotics, potentially spreading antimicrobial resistance. The finding raises concerns because people may be exposed to both microplastics and the drugs they carry through contaminated water and food.

The study highlights the compounding food safety risks when multiple pollutants interact in aquaculture environments.
Microplastics as Potential Vector of Antibiotics in Aquatic Media: Environmental Implications
This review examined the role of microplastics as vectors for antibiotics in aquatic environments, highlighting how their small size, large surface area, and hydrophobicity enable them to concentrate organic pollutants. Co-exposure of microplastics and antibiotics can enhance bioaccumulation in organisms and amplify environmental risk.
Quantitative assessment of interactions of hydrophilic organic contaminants with microplastics in natural water environment
Researchers quantified how microplastics interact with common antibiotic pollutants in natural water conditions, comparing virgin and environmentally aged polystyrene particles. They found that aged microplastics absorbed significantly more antibiotics than new ones due to increased surface area and chemical changes from weathering. The study suggests that as microplastics age in the environment, they become more effective at concentrating and transporting other harmful pollutants.
Interaction between antibiotics and microplastics: Recent advances and perspective
This review examines how microplastics in water can absorb antibiotic pollutants onto their surface, especially as the plastics age and develop bacterial biofilms.

Sorption of antibiotics onto aged microplastics in freshwater and seawater
Aged microplastics were found to sorb antibiotics from fresh and saltwater, with aging processes altering the surface properties of the plastic and increasing antibiotic binding capacity in some cases. The adsorption of antibiotics onto aged microplastics could facilitate their transport and delivery to aquatic organisms, potentially contributing to antibiotic resistance in environmental bacteria.
Effects of aged microplastics on the abundance of antibiotic resistance genes in oysters and their excreta
Researchers studied how aged microplastics affect the abundance of antibiotic resistance genes in oysters and their excreta.

Farmed stage (age)-dependent accumulation and size of microplastics in Litopenaeus vannamei shrimp reared in a super-intensive controlled system
Researchers tracked microplastic accumulation in farmed shrimp over their entire growth cycle and found that both the number and size of microplastic particles increased as the shrimp grew older. Shrimp raised in super-intensive indoor systems had higher microplastic contamination than those from traditional ponds or wild environments, likely due to the extensive plastic materials used in the farming infrastructure. Since shrimp is widely consumed seafood, these findings mean that people eating farmed shrimp are likely consuming microplastics that accumulated throughout the animals' lives.
Assessment of bioavailability of microplastic-sorbed tetracycline to bacteria for activation of antibiotic resistance genes in water environments
Researchers examined whether antibiotics adsorbed onto microplastics retain their biological activity against bacteria in water environments. They found that tetracycline bound to microplastic surfaces remained bioavailable enough to promote the activation of antibiotic resistance genes in aquatic bacteria. The study suggests that microplastics carrying adsorbed antibiotics may contribute to the spread of antimicrobial resistance in water systems rather than simply immobilizing the drugs.
